Does longer U-joint service life sound good to you? Well, Dana utilized the 2017 SEMA Show in Las Vegas to unveil its new Spicer Blue-Coated Performance U-joints that incorporate the company’s Spicer Life Series (SPL) technology. Dana says these new U-joints have been tested to deliver significantly more service life than competitive U-joints. In testing at the Dana engineering laboratories, Spicer 1310 Series U-joints with SPL technology were fatigue-tested to more than 1,000,000 cycles without failure. By comparison, Dana says that the nearest competitive U-joint tested achieved an average of 106,746 cycles before failure.

The distinctive blue coating on the journal cross of the Spicer Blue-Coated Performance U-joints also has been shown to resist rust and corrosion in salt and mud testing.

The Spicer Blue-Coated Performance U-joints include a journal cross engineered with a solid cold-formed body to ensure better wear and overall strength; bearing cups that are heat-treated for strength and precision-ground and case-hardened for durability; thrust washers that eliminate metal-to-metal contact, prevent wear, and lower the overall operating temperature; a multi-lip seal to keep grease in and contaminants out, and to attain maximum retention in a wider range of environments; and there’s a multi-lip seal that includes a seal guard for optimal protection. These U-joints are lubed-for-life for maintenance-free operation.

Initially, Dana Blue-Coated Performance U-joints will be available in five common sizes—5-760XC, SPL30-7166XC, SPL30-1350XC, SPL55-1480XC, and SPL70-1550XC—for some of the most popular 4X4 vehicles, including Jeep Wrangler and Ford Super Duty. Additional applications may be added in the future.
